Functions

func And

func And(lhs, rhs *cb.SignaturePolicy) *cb.SignaturePolicy

And is a convenience method which utilizes NOutOf to produce And equivalent behavior

func FromString

func FromString(policy string) (*cb.SignaturePolicyEnvelope, error)

FromString takes a string representation of the policy, parses it and returns a SignaturePolicyEnvelope that implements that policy. The supported language is as follows:

GATE(P[, P])

where:

• GATE is either "and" or "or"
• P is either a principal or another nested call to GATE

A principal is defined as:

ORG.ROLE

where:

• ORG is a string (representing the MSP identifier)
• ROLE takes the value of any of the RoleXXX constants representing the required role

func NOutOf

func NOutOf(n int32, policies []*cb.SignaturePolicy) *cb.SignaturePolicy

NOutOf creates a policy which requires N out of the slice of policies to evaluate to true

func Or

func Or(lhs, rhs *cb.SignaturePolicy) *cb.SignaturePolicy

Or is a convenience method which utilizes NOutOf to produce Or equivalent behavior

func SignedBy

func SignedBy(index int32) *cb.SignaturePolicy

SignedBy creates a SignaturePolicy requiring a given signer's signature
